Gerard Pique has been booed during the Madrid Open match between David Ferrer and Mikhail Kukushkin as Real Madrid supporters made the Barcelona star feel unwelcome.

The Spain centre-back has a frosty relationship with Madridistas for his persistent trolling of Los Blancos and took time out to visit the capital on a day off.

Despite cheering on compatriot Ferrer, Pique was spotted by fans on the big screen during the first round match.

Ferrer took it in three sets (2-6, 7-6, 6-4) with Pique receiving plenty of stick after trolling Real in recent weeks.

The most recent incidents came last month when the 30-year-old tweeted shortly after Cristiano Ronaldo scored an offside goal at a pivotal stage of the Champions League quarter-final against Bayern Munich.

The timing of the tweet, which only included three full stops, clearly suggested he thought Los Merengues were receiving preferential treatment.

Pique then engaged in a war of words with La Furia Roja team-mate and Madrid stalwart Sergio Ramos, who snapped back at him after being handed his marching orders in el clasico for a horrendous challenge on Lionel Messi.
